MACHINE FOR BREASTING- I-IEELS.

To all whom it may concern:

Be it known that I, JOSEPH GoULnBoURN, a subject of the King of England,residing at Leicester, in the county of Leicester, England, haveinvented certain Improvements in Machines for Breasting Heels, of whichthe following description, in connection with the accompanying drawings,is a specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to machines fo breasting heels. l

The present application constitutes a division of an application iiledJuly 10, 1906, Serial No. 325,516.

The machine shown herein comprises a Work support for sustaining a heelin position to be acted upon and a cutter arranged for movement alongthe face to be trimmed. Mechanism is provided for guiding the cutter ina predetermined path across the breast of a heel, and the arrangement issuch that the breasts of heels may be trimmed to various contours byadjustment of the ma.- chine. The construction herein described is suchthat the contour produced may be either concave, convex or straight, andthe degree of conveXity or concavity may be varied as desired.

The particular construction shown herein comprises a work support, amovable cuttercarrying member, and mechanism for controlling themovement of said member, adapted to cause two separated points on saidmember to have a simultaneous'traverse along paths which are straightand angularly disposed to each other. It will be found that by suitablylocating the cutter upon its supporting member the path of the cuttermay be made convex or concave with relation to the breast of the heel,or, if desired, may be rectilinear to give the breast of the heel astraight contour. To permit the depth of cut of the cutter to bevariedas desired, the work supporting member is arranged for adjustmentto permit the work to be moved into or out of the range of the cutter.

Other features of the invention, including details of construction andcombinations of par-ts, will be hereinafter described and defined in theclaims.

In the drawings,-Figure 1 is a side elevation of part of aheel-breasting machine Specification of Letters Patent.

Patented Aug. 23, 1910. Divided and this application filed OctoberSerial No. 395,904.

showing the present invention wherein the heel is stationary and thecutter is mounted in bearings supported upon a movable member or plate;F ig. 2 is a front elevation of the parts shown in Fig. 1; Fig. 3 is asectional view of the cutter, member or plate, and adjacent parts on theline 3--3 of Fig. 1; Fig. 4 is a sectional detail view on the line 4-4of Fig. 1.

Referring to the drawings, in the construction illustrated therein aheel carrier 12 is mounted directly upon the machine frame 13 and arotary cutter 14 is carried by a controlling plate 16 provided with ahandle 18 by means of which it may be moved by the operator to bring thecutter into engagement with and to cause it to travel past the heel 20to effect the breasting of the same. The path of motion traversed by thecutter is controlled by two rollers 22, 24, mounted upon the studs 26,28 screwed into the controlling plate, which rollers engage respectivelywith two cam grooves 30, 32 formed in the machine frame. To retain thecontrolling plate in position on the machine frame it has three lugs 34,which engage respectively with surfaces 36 and overhanging flanges 3Sformed upon the ma chine frame 13.

With the parts adjusted as shown, the operation of the machine is asfollows The handle 13 is moved downwardly causing the controlling plate16 first to swing about the roller 24 on the stud 2S as a center whilethe roller 22 on the stud 26 is traveling along the curved part of thecam groove 30 thus bringing the cutter into engagement with the cornerof the breast of the heel. A continued downward movement of the handle18 neXt causes the rollers to travel along the grooves 30, 32 andthereby so guide the cont-rolling plate that the center of the cuttertravels in substantially a straight line and consequently thecutter iscaused to breast the heel with a straight cut.

Vhen it is desired to give a concave curvature to the breast of the heelthe cutter is adjusted to a position o-n the controlling plate 16 nearerto the grooves 30, 32 than that in which it is shown in Fig. 1. But thisadjustment of the cutter will necessitate an adjustment of the positionof the heel carrier 12 on the machine frame; otherwise the cutter willbe too far within range of the heel 20. In order that these adjustmentsmay be readily obtained both cutter and heel carrier are adjustablymounted upon the parts that support them. The heel carrier 12 isprovided with a heel-clamp 15, pivoted at 17 to the carrier 12 andhaving its free end adapted to bear by way of a contact piece 19 uponthe seat of a heel 20, the top lift of the latter' resting upon thecarrier 12. The clamp is operated by the adjustable link 21 connected toit at 23 and also connected to the carrier. This heel carrier is mountedin guideways 40 on the machine frame and is provided with an adjustingdevice 42 comprising a. screw engaging a screw-threaded lug on themachine and connected to the carrier by a pin and groove connection. Thecutter is secured to a shaft 44 carried in bearings on a slide 46mounted in guideways in the controlling plate.

An adjusting device 48, similarl to the device 42, is provided to enablethe slide 46 and cutter 14 to be adjusted on the controlling plate. Thecutter is driven from any suitable source of power by a belt eX- tendingover a pulley 52 fast upon the shaft 44, any usual belt-tighteningdevice being employed to obtain the desired tension of the belt on thepulley 54 during the movement of the cutter. It will be understood thatif it is desired to impart a convex curvature to the breast of the heelthe cutter 14 will be adjusted to a position farther from the grooves30, 32 than that in which it is shown in Fig. 1.

The path of relative motion of the heelcarrying member and thecutter-carrying member obviously may be controlled by cam slots otherthan those shown; for instance, three slots of a similar shape to thelugs 34, Fig. 1; but to enable the heel to be breasted to any curvaturefrom that of the cutter to a straight line or even a convex curvature,these slots must be arranged so that two points-for example, 26, 28-onthe cuttercarrying member move in paths which are straight and angularlydisposed to each other or are non-concentric- Having described myinvention, what I claim as new and desire to secure by Letters Patent ofthe United States is 1. A heel-breasting machine having in combinationmeans for sustaining a heel to be acted upon, Va cutter movable fromside to side of the heel, and mechanism for guiding thecutter in apredetermined path, said mechanism being arranged for adjustment topermit said path to be either straight or curved.

2. A heel-breasting machine having in combination means for sustaining aheel to be acted upon, a cutter, and mechanism for guiding the cutter ina curved path from side to side of the heel, said mechanism beingarranged for adjustment to permit the direction of curvature of saidpath to be varied.

3. In a machine of the class described, the combination with acutter-carrying member and a heel-carrying member arranged for relativetraversing movement, of mechanism for constraining two separate pointson the cutter-carrying member along paths.- which are straight andangularly disposed" to each other.

4. A machine for trimming heels having in combination means forsustaining a heel to be acted upon, a cutter movable along the face tobe trimmed, and mechanism for guiding the cutter in a predeterminedpath, said mechanism being arranged for adjustment to permit said pathto be either straight or curved.

5. A heel-breasting machine having in combination means for sustaining aheel to be acted upon, a rotary cutter arranged for movement from sideto side of the heel, and means for guiding said cutter arranged to varyits path whereby to impart a straight or curved contour to the breast ofa heel.

6. A heel-breasting machine having in combination a frame, a worksupport thereon, a movable controlling member carrying a cutter andmeans for guiding said member to impart to the cutter a movement in apredetermined path relatively to the work support, the cutter beingarranged for adjustment relatively to said means whereby the directionof curvature of said path may be varied.

7. A heel breasting machine having in combination a frame, a worksupport thereon, a movable controlling member carrying a cutter, meansfor guiding said member to impart to the cutter a movement in apredetermined path along the breast of a heel carried by said support,means permitting adjustment of the cutter relatively to said means tovary said ath, and means permitting adjustment of the work support tomaintain it in proper relation to the cutter.

8. A heel breasting machine having in combination a frame, a worksupport thereon, a movable controlling member carrying a cutter,mechanism comprising angularly disposed grooves and studs tting saidgrooves arranged between said frame and controllin member for guidingsaid cutter in a pre etermined path relatively to the work support, andmeans permitting adjustment of the cutter relatively to said mechanismwhereby to vary said path.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
